2 and 3rd question answer, plss i am struggling..
10th grade

Answer 1

Answer:

42 ohm

Explanation:

Produce B and C

Now 40 ohm and 100 ohm are connected in series(because they are having one common end A)

Now 40+100=140ohm

draw resistor of 140 ohm parallel to 60 ohm

you will find that 140 ohm and 60 ohm are connected in parallel (because they are having 2 common end B and C)

Now you have to calculate R effective between B and C

1/Re=1/R1+1/R2=(R1+R2)/R1R2

1/Re=(140+60)/140*60

1/Re=200/140*60

1/Re=1/42

Re=42ohm

Answer 2

Explanation:

A pair of corresponding angles lie on the same side of the transversal. The corresponding pair of angles comprises one exterior angle and another interior angle. Not all corresponding angles are equal. Corresponding angles are equal if the transversal intersects two parallel lines.
